A first electrode is attached to the footrope of an otter-type shrimp trawl net and a second electrode is attached to the tickler chain of the net. The two electrodes are periodically energized by a power supply located on the towing boat which charges and discharges a capacitor located on one of the otter doors of the net. The capacitor periodically discharges through the two electrodes and stimulates shrimp embedded in the surface of the sea bottom lying between the electrodes.
